Nice location - handy for Elecraft too. there is a tree in the background that looks tempting as an antenna support. At the moment it looks like you have one of those QTHs with almost no man-made noise which coupled with an inefficient 80m antenna is frustrating when people you can hear perfectly well can't hear you.
The remote auto-tuner at the base is in exactly the right place, but you will need to give it some help. Adding an extra coil at the base which you can bypass with relays will probably allow you to tune the vertical on 80m. Not ideal but it will be better than an 80m mobile whip and they work to some extent. The KPA500 will then help overcome the poor radiation efficiency. With 600W, you need to ensure the coil will handle the power, but that's not so hard to achieve. It does not need to be a coil, you could use a phasing line along the fence instead. Even if the K3 will tune it, there might be significant feeder losses and you are down on power without the linear.
